permission denied installing package (make files)

Hi everyone,

Im new here and new to this version of Linux. Im running a new install of Fedora core 11.
Im in the process of setting everything up as a home server full blown from my home.
It's dls. 

I was trying to get ddclient to work. I got it all setup. Then I get error
saying it requires IO::Socket::SSL and it's not installed. I searched the web
for all the info I could, and found cpan. I downloaded NET::SSLeay and ran 
Makefile.PL (./Makefile.PL) it installed just fine. 

So I went back and downloaded some more of them. I tried to make and install them.
I got permission denied. oops I needed to be root. So I su root. Tried again.
permission denied. I logged out and logged in directly as root. permission denied.

can anyone please help with this? 

I have programed in perl along time agao apparently thing have changed alot.
I also programed in C++.

I also would like a little more info on getting cpan and install in on this machine aswell

please email this directly to me if you would

Thanks in advance
